TECHNISCHES GEBIETTECHNICAL AREA
Das vorliegende Gebrauchsmuster betrifft das technische Gebiet der elektronischen Ausrüstung, insbesondere ein Versuchsgerät, mit dem eine auf dem Energiespeicher basierte doppelt gespeiste Windkraftanlage an der primären Frequenzmodulation des Systems teilnimmt.The present utility model relates to the technical field of electronic equipment, in particular an experimental device with which a double-fed wind turbine based on the energy storage device participates in the primary frequency modulation of the system.
STAND DER TECHNIKSTATE OF THE ART
Seit den letzten Jahren stehen die Probleme wie Energiekrise, Umweltverschmutzung immer hervor. Aufgrund der Förderung der Entwicklung und Nutzung erneuerbarer Energien zieht die verteilte Erzeugungstechnologie (Distributed Generation, DG) immer mehr Aufmerksamkeit auf sich, sie hat die Vorteile weniger Umweltverschmutzung, einer hoher Nutzungsrate der Energie und eines flexiblen Einbauorts. Mit der kontinuierlichen Zunahme der Durchdringungsrate der verteilten Stromquelle hat dies jedoch große negative Auswirkungen auf die Planung und den Betrieb des Stromnetzes.In recent years, the problems such as energy crisis, environmental pollution are always prominent. Due to the promotion of the development and use of renewable energy, the distributed generation technology (DG) attracts more and more attention, it has the advantages of less pollution, high utilization rate of energy and flexible installation location. However, with the continuous increase in the penetration rate of the distributed power source, it has a great negative impact on the design and operation of the power grid.
Die meisten verteilten Stromquellen haben keine Trägheitseigenschaften, und die plötzliche Laständerung bewirkt, dass sich die Ausgangsfrequenz des Wechselrichters abrupt ändert, was der Frequenzstabilität des Microgrid-Systems nicht zuträglich ist. Um das Problem zu lösen, wird ein Gerät, mit dem eine energiespeicherbasierte doppelt gespeiste Windkraftanlage an der primären Frequenzmodulation des Systems teilnimmt, zur Verfügung gestellt.Most distributed power sources have no inertia characteristics, and the sudden load change will cause the inverter output frequency to change abruptly, which is not conducive to the frequency stability of the microgrid system. To solve the problem, a device that allows an energy storage-based doubly-fed wind turbine to participate in the system's primary frequency modulation is provided.
INHALT DES VORLIEGENDEN GEBRAUCHSMUSTERESCONTENT OF PRESENT UTILITY MODEL
Das vorliegende Gebrauchsmuster zielt darauf ab, das Problem der bestehenden doppelt gespeisten Windkraftanlagen, dass sie nicht an der primären Frequenzmodulation des Systems teilnehmen kann, zu lösen. Die spezifische technische Lösung ist wie folgt.The present utility model aims to solve the problem of the existing double-fed wind turbines that they cannot participate in the primary frequency modulation of the system. The specific technical solution is as follows.
Ein Versuchsgerät, mit dem eine energiespeicherbasierte doppelt gespeiste Windkraftanlage an der primären Frequenzmodulation des Systems teilnimmt, dadurch gekennzeichnet, dass es den optimalen Verbindungsmodus des Superkondensatormoduls nutzt, um die Zuverlässigkeit dieses Geräts zu verbessern und die durch den Kapazitätsdispersionsgrad erzeugten Auswirkungen zu verringern. Darüber hinaus nimmt der Stromrichterschrank die Struktur an, in der die Erregungssteuerung und der netzseitige Wechselrichters integriert sind. Der Hauptzweck der PWM-Erregung und Frequenzumwandlung besteht darin, den Erregerstrom für die Rotorwicklung bereitzustellen. Der netzseitige Stromrichter ist eine bidirektionale Stromversorgung, die die elektrische Energie umkehren oder gleichrichten kann.An experimental device with which an energy storage-based doubly-fed wind turbine participates in the primary frequency modulation of the system, characterized in that it uses the optimal connection mode of the supercapacitor module to improve the reliability of this device and reduce the effects generated by the capacitance degree of dispersion. In addition, the converter cabinet adopts the structure in which the excitation controller and grid-side inverter are integrated. The main purpose of PWM excitation and frequency conversion is to provide the excitation current for the rotor winding. The line-side power converter is a bi-directional power supply that can reverse or rectify electrical energy.
Das Superkondensatormodul nimmt den Verbindungsmodus mit zuerst der Parallelschaltung und dann der Reihenschaltung mit guter Zuverlässigkeit an, und der Kapazitätsdispersionsgrad ist geringer, und dieses Array hat geringere Anforderungen an die Ausgleichsfähigkeit der Spannungsausgleichsschaltung.The supercapacitor module adopts the connection mode with first the parallel connection and then the series connection, with good reliability, and the degree of capacitance dispersion is lower, and this array has lower demands on the balancing ability of the voltage balancing circuit.
Der DSP-Chip des Steuergeräts basiert auf DSP 28335 der Firma TI. Die Hauptschaltung des Rotors und des netzseitigen Stromrichters nimmt eine dreiphasige Vollbrückentopologie an, wobei das Schaltgerät Mitsubishi IPM annimmt.The DSP chip of the control unit is based on the DSP 28335 from TI. The main circuit of the rotor and the line-side power converter adopts a three-phase full-bridge topology, with the switching device adopting Mitsubishi IPM.
Die Stromversorgungsschaltung des Steuerteils nimmt den dreipoligen Spannungsreglerchip der Serien 78xx und 79xx, um eine Gleichstromversorgung zu erzeugen.The power supply circuit of the control part adopts the 78xx and 79xx series three-pin voltage regulator chip to generate a DC power supply.
